COMBINED CHURN AND ICE-CREAM FREEZER.

SPECIFICATION forming part of Letters Patent No. 642,103, dated January30, 1900.

Application filed October 5, 1899.

To aZZ whom it 72mg concern.-

Be it known that I, CHARLES J. EDDY, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in a Combined Churn andIce- Cream Freezer, of which the following is a specification.

My invention relates to a combined icecream freezer and churn, theprincipal object of my invention being to produce a device that willinsure either the quick freezing of cream, as a freezer, or the churningof cream to produce butter, as a churner. The device is suspended fromframes, so that the cream will be agitated by giving the device aswinging motion.

In the drawings, Figure 1 is a transverse sectional View of myinvention. Fig. 2 is a cross-sectional view of same. Figs. 3 and 4. aredetail views of parts of my device.

Like parts are represented by similar letters of reference in theseveral views.

In said drawings, a represents an outer cylindrical can, preferablyconstructed of sheet metal and of any desired size, according to therequired capacity of the machine, said can being closed at one end andhaving a central circular opening at the opposite end thereof, whichopening is provided with screw-threads a. Said outer cylindrical can ais suspended from frames 6 by links or wires cl, threaded through thebearings cl and hooked at each end to the eyes or hooks of the frame e,as shown in Fig. 2. p

The inner can or cream-receptacle b, which is of considerably smallerdiameter and shorter in length than the outer can a, is introducedthrough the opening in said outer can, and thereby a space I) is thusformed between the inner and outer cans which can be filled with waterwhen churning is desired and with ice when the machine is to operate asa freezer. The open end of the inner can b is also provided withscrew-threads which conform to the threads a of the outer can andaccordingly secure the can b in a rigid position. Said inner can orcream-receptacle is supported by a ringb which extends around saidreceptacle near its closed end,as shown in Figs. 1 and 2. Then the partsare assembled together, the threaded end of the cam b pro- Serial No.732.616. (No model.)

jects somewhat beyond the end of said outer can a, the projectingportion being provided with a screw-cap b which prevents the contents ofcan b leaking out. Said screw-cap b is in turn provided with a handleI)", which is intended to be used in screwing or unscrewing the cap 6and operating the machine during the process of churning or freezingcream. When the machine is to be used as a churn, a dasher is placedwithin said inner receptacle b, which dasher consists of a central rod0, with three or more metal disks 0, c and c secured thereto, and allsaid disks excepting the one nearest the closed end of said receptacleare provided with openings, as shown in Fig. 4c, the said disks nearestthe closed end being solid, with no openings whatsoever.

,It is thus readily seen that after the cream has been churned byremoving the dasher, with said metal disks, from the inner can orreceptacle 1) the butter will be collected upon the said metal disks.

The bearings d d at each end of the outer can, with the hooked links 01ct arranged as shown in Figs. 1 and 2, act as braces to prevent any sidemotion of the machine, and in order that the cans may be placed in anupright position when filled or emptied or for cleaning purposes saidlinks are readily unhooked from the rings or eyes on the frame e. Theopening 6 at the top of the outer can, as shown in Fig. 1, permits thespace I) to be filled with water during churning, which will keep thecream at an even temperature, or when the machine is used as a freezersaid space I) may be filled with ice and salt. The vent or opening f,fitted with a screw-cap near the bottom of said outer can, is fordraining said can.

It will thus be seen that I have constructed a simple and extremelyuseful machine which can readily bechanged from a churning-machine to afreezing-machine, or Vice versa.

Having thus described my invention, I claim-- 1. The combination of anouter can open at one end, supports for said can and links socuring saidcan to said supports, and formed to permit a longitudinal movement onlyof said can, an inner receptacle of less diameter and shorter in lengththan said outer can, open at one end and adapted to be supported can,closed at one end and screw-threaded atv its open end and adapted to besupported within said outer receptacle at its closed end, and having itsopen end screw-threaded into the open end of said outer can, andprojecting slightly beyond the same, and a screw threaded cap fittingonto the screw-threaded end of said inner can, substantiall'yas speci-3. The combination of an outer can sup ported in a suitable frame,formed with an opening at one end, an opening in the top of said outercan and a small opening at or near the bottom thereof, closed by a cap,an inner receptacle supported in said outer can, said inner receptaclebeing open at one end, the open end of Which projects slightly throughand is supported in the opening in said outer can, a cap on one end ofsaid inner recep tacle and means for producing a longitudinal movementof said outer can in its supportingframe, substantially as specified.

In testimony whereof I have hereunto set my hand this 2d day of October,A. D. 1899.

CHARLES J. EDDY.
